Instant installation with accuracy you can count on.
If you race sailboats, the benefits of an accurate speedometer are probably already fairly obvious to you. Even still, you might not sail with a speedo because you can’t be bothered to drill holes in your hull and wire-up a paddlewheel transducer. The award winning SpeedPuck is completely self contained and can be installed in seconds, without tools. Instead of using a paddlewheel, the SpeedPuck calculates your speed by measuring the Doppler shift in GPS signals to provide you with an updated reading twice a second. The SpeedPuck never needs to be calibrated and maintains uniform accuracy at all speeds.
The Speedpuck is Simple and Easy to use with a large display that can be read in the toughest sailing conditions, this is the only gps instrument you need for sailboat racing and training. One of the greatest things about the speed puck is that it can be easily taken from boat to boat unlike hardwired transducer units. The speed puck is a great tool for any sailor looking to sail fast!
